Boyfriend teases and picks on me too much? *Fart story and also, share your own?

He is very playful and fun to be around. Love him deeply and dearly and we never stop laughing together and having a great time! It's like having a best friend and boyfriend in one. But the other day he kept teasing me mercilessly because I farted when we were play fighting while he was tickling me and it was so mean how he kept going on and on about it and threatening to tell our mutual friends. Like shortly after it happened, our friend came over and he kept making it seem like he would tell him what happend. I was fighting with him to stay quiet and would keep cutting him off like "He just wanted to tell you we have some food in the fridge if you want some." He was dying laughing and I was too but more out of embarrassment and was begging him to keep his mouth shut! He does this all the time about everything! Like I can't do one human thing without him wanting to tell the world and laughing his ass off. I'm so embarrassed and especially because it's the first time I've ever farted in front of him in our entire relationship of 10 months. He brought it up again when my shoe made a noise against the chair and he was like "Is that you tooting?" I was laughing but so annoyed because it happened ONE time. Like he needs to get over it and stop embarrassing me! And then he always complains that other guys flirt with me too much and I'm too 'cute' so he was like "I'll tell everyone so that guys stop hitting on you." I know he's just joking around but I pride myself on being a girlie girl and love dressing up and he knows how much it bothers me that it happened in his presence. What should I do and how do I make it seem like it doesn't bother me? I always told him I would never ever fart in front of him and now I have to take back those words and swallow by pride because it happened and he'll always have this memory LOL. Also what are the chances he'll forget this ever happened? LOL
